WASHING-MACHINE FOR PAPER-STOCK.

SPECIFICATION forming part of Letters Patent No. 569,673, dated October20, 1896.

Application filed Cletober 3, 1895. Serial No. 564,617. (No model) To (0whom it may concern.-

Be it known that I, MICHAEL J. ROACH, of Anderson, Madison county,Indiana, have invented certain new and useful Improvements in\Vashing-llachines for Paper-Stock, of which the following is aspecification.

This invention pertains to improvements in machines for washingpaper-makers stock, particularly straw stock.

My improvements will be readily understood from the followingdescription, taken in connection with the accompanying drawings, inwhich- Figure 1 is a side elevation of a machine exemplifying myinvention 3 Fig. 2, a vertical longitudinal section of the same; Fig. 3,a vertical transverse section of the same; and Fig. 4, a verticallongitudinal detail section, partly broken away, showing the dipperarran gement.

In the drawings, 1 indicates a horizontal conical casin g made,preferably, in two halves united by a horizontal joint; 2, aninlet-opening at the smaller end of the casing to admit the stock. whichis to be washed; 3, an outletopening at the larger end of the casing forthe'discharge of the washed stock; 4, a hol- 10w conical revolvermounted to turn within the casing, the periphery of this revolver beingforaminous by being formed of wire-cloth or perforated metal, which willpermit the passage inwardly of water, but not of stock, the revolverbeing built up on spiders and skeleton framing, as is usual in theconstruc tion of wire-cloth cylinders used in papermills; 5, the shaftof the revolver; 6, the driving-pulleyof the revolver, fast on shaft 5;7, a water-discharge pipe leading into the interior of the revolver 4;8, clearing-dippers, of ordinary construction, arranged within therevolver and turning with it and communieating with discharge-pipe 7, soas to carry outwardly the water accumulating in the revolver; U, screwfor adjusting the revolver endwise in the casing in order to increase ordecrease the width of the annular space within the casing around therevolver; 10, longitudinal side pipes cast upon the exterior of thecasing; 11, water-inlet pipes placing the side pipes in communicationwith any proper source of free supply of washing-waterg 12, longitudinalslots through the wall of the casing at the side pipes to admit waterfrom the side pipes to the space around the revolver freely from end toend; 13, the lower portion or floor of the casing, in grate form, andarranged to open downwardly to give access to its interior surface; 14,a foraminous lining for the openable floor port-ion of the casing, thislining being formed of perforated metal or wire-cloth adapted to permitthe outward passage of water, but prevent the outward passage of stock;15, spiders, one at each end of the revolver a and loose on the shaft ornecks of the revolver, so as to be capable of turning independent of therevolver; 16, a series of ribs spirally arranged and having their endssecured to the spiders 15, these ribs turning in the annular spacearound the revolver and clear of the revolver and of the casing 17, ahollow shaft loose on the shaft of the revolver and fast with one of thespiders 15 and projecting out through one end of the casing, and 18 adriving-pulley fast on the hollow shaft 1'7.

Rotary motion in the same direction may be given to the revolver and tothe ribs at different speeds. The stock to be washed is admitted atopening 2 and moves toward the larger end of the machine, being urged bycentrifugal force and by the action of the ribs 16. \Vashing-waterenters through slots 12, the stock receiving fresh clean water as itmoves toward the large end of the casing. The stock is carried around inthe annular space and tumbled and turned and moved endwise, much of thedirty washing-water leaving through the foraminous floor of the casingand much of it passing into the interior of the revolver, whence it isdrawn off through pipe 7. Cleaned stock leaves at opening 3. Thewashing, it will be observed, is done between two foraminous surfacesover which the stock is rubbed by the action of the spiral ribs. Theribs may be given any desired speed with relation to the speed of therevolver so as to accomplish the washing in the best manner and feedforward the stock at desired rate. Power may be applied to the machineby separate belts on pulleys 6 and 18, or, for a fixed relationship ofspeed, suitable gearing maybe employed in connection with a single beltfor giving the differential speeds. The dippers 8 may, if desired,

be dispensed with and the water drawn from the interior of the revolverthrough pipe 7, employed as an ordinary dip-pipe, that is to say, withan end within the revolver dipping down to near its wall, as in the caseof a single dipper maintaining a fixed downward position.

I claim as my invention- 1. The combination, substantially as set forth,of a circular casin g having an inlet and an outlet for stock, a hollowrevolver mounted therein and having a foraminons periphery, a series ofribs mounted to turn in the annular space within the casing and aroundthe revolver, means for turning said revolver and series of ribsindependently, and an inlet and outlet for washing-water.

2. The combination with a casing provided with an inlet and outlet forstock at its op posite ends and with a longitudinal waterinlet openingor slot extending continuously, substantially from end to end of thecasing, the edge of said opening constituting a ledge against which thestock is dashed and separated, and a supply-pipe or conduit designed tosupply water to the inlet-opening along its entire length tosimultaneously dislodge the stock adhering to the ledge and to supplythe interior of the casing with water, and a revolver within the casingdesigned to agitate the stock.

3. The combination, substantially as set forth, of a circular casinghaving an inlet and outlet for stock and having a foraininous wallportion, a circular revolver mounted in the casing and having aforaminous periphery, and a series of ribs mounted to travelindependently in the annular space between the casing and revolver.

4. The combination, substantially as set forth, of a circular conicalcasing, a conical casing mounted to turn therein and having a foraminousperiphery, a dipper within the larger end of the revolver, and adischarge pipe com municating with said dipper.
